Using the fast charger
Fast charger indicators are described in Table
E-3.
Table E-3: Fast charger indicators
Charging the battery using the fast
charger
Charging using the fast charger involves three
stages.
■ The fast charge stage quickly brings the
battery up to near its full capacity. The
charger LED will glow red.
■ The trickle stage slowly tops up the battery
until it is at its full capacity, which is
typically 1½ hours. The charger LED will
flash green.
■ The standby charge stage keeps the
battery at its full capacity, as long as the
radio is turned off. The charger LED will
glow green.
The battery can be charged separately or
attached to the radio. The radio must be
turned off to ensure a full charge.
Turn off the radio and insert the battery/radio
into the charger. If the indicator does not glow
red, make sure the battery/radio is seated
properly and the charger is plugged in correct-
ly. If the battery is too hot or too cold, the
indicator will remain amber until the battery
temperature is within the safe range for
recharging (5°C to 40°C).
Approximate charge times are:
■ up to 1½ hours for TOPB100 and
TOPB600;
■ up to 2 hours for TOPB200, TOPB400 and
TOPB700; and
■ up to 2½ hours for TOPB500.
Once the battery has reached approximately
90% capacity, the indicator will flash green. At
this point, it is recommended the battery be
left in the charger for a further 1 to 2 hours, to
ensure maximum battery charge. Once the
battery is fully charged, the indicator will glow
green.Avoid leaving charged batteries in the
charger for more than a day.
Conditioning the battery with the fast
charger
Two conditioning functions are available on
the fast charger, a short conditioning cycle and
a long conditioning cycle. The short cycle
discharges the battery then charges it. Regular-
ly recharging a battery that has not been
completely discharged will eventually affect its
ability to hold a full charge.
For best performance, the battery should be
conditioned weekly using the fast charger.
Conditioning the battery takes about four to
eight hours, depending on how much use it has
had.
Note
NoteNote
Note: Do not use the short conditioning cycle
on a new battery without first fully charging it
using a long conditioning cycle.
The long conditioning cycle is necessary:
■ before the battery is used for the first time;
■ if the battery performance has deteriorat-
ed; or
■ after the battery has been stored for longer
than two weeks.
